Connecting 48 Vdc Power for PoE Operation Connecting 48 Vdc Power for PoE Operation The Matrix N5 (7C105‐P) chassis provides 48 Vdc to connected PDs (powered devices) by way of its backplane connection to a PoE‐compliant DFE module such as the 4G4285‐49 or 4G4205‐72. For a Matrix E7 (6C107), Matrix N3 (7C103), and Matrix N7 (7C107) chassis, an optional external Enterasys Matrix N‐POE Power System is required to support PD connections to the 4G4285‐49.
Connecting to the Network Connecting to the Network Warning: The DFE module is shipped with a cover over its 48 Vdc Optional Power Input connector. Do not remove this cover when the DFE module is installed in an N5 chassis. This cover is removed only when you connect a 48 Vdc power cable from the Enterasys N-POE Power System. Advertencia: El modulo DFE es embarcado con una cubierta sobre su conector de poder opcional de 48 Vdc. No remover esta cubierta cuando el modulo DFE es instalado en un chassis N5.
Connecting to the Network The RJ45 fixed front panel connectors of the 4G4285‐49 and 4G4205‐72 also support PoE‐compliant connections to PDs (powered devices) that require 48 Vdc through the UTP cable to operate. When the 48 Vdc is available through the backplane of an N5 chassis or externally from an N‐POE Power System, you can verify if there is power at each port as described later in this procedure.
Connecting to the Network 3. Verify that a link exists by checking that the port RX (Receive) LED is ON (flashing amber, blinking green, or solid green). If the RX LED is OFF and the TX (Transmit) LED is not blinking amber, perform the following steps until it is on: Note: If the RX and TX LEDs of a port do not indicate a link and the end-point device is a PD, you may have a port without 48 Vdc to operate the PD. To check the PoE Port Status, refer to “Verifying PoE Port Status” on page 3-19. a.

C About PoE (Power over Ethernet) This appendix provides an overview of Power over Ethernet Technology and how it is implemented in relation to the 4G4285‐49 and 4G4205‐72 DFE modules. Overview Power over Ethernet (PoE) refers to the ability to provide operational power through the same Ethernet cabling to a PD (powered device) connected to a data network. Modern Ethernet implementations employ differential signals over twisted pair cables.
Overview Proprietary PD Detection The 4G4285‐49 and 4G4205‐72 support a subset of the currently deployed proprietary PoE methods. This includes support for Cisco PDs, including a proprietary capacitor based detection scheme. Power Interface The 4G4285‐49 and 4G4205‐72 can interface with an external 48V power supply that resides in a Matrix N5 chassis. Matrix N5 Backplane 48 Vdc Interface The 4G4285‐49 and 4G4205‐72 have a connector that interfaces with the backplane of the N5 chassis for 48 Vdc power.
Overview Front Panel 48 Vdc Interface The 48 Vdc Optional Power Input connector on the 4G4285‐49 front panel provides a power interface connection for an Enterasys Matrix N‐POE Power System, which provides the 48 Vdc, 20 Amperes of power and return as well as the power supply status signals. The status signals indicate the presence and operating state of each Matrix N‐POE Power System power supplies.
